Lu Tingchen was reborn and returned to the day when he personally pushed his wife down the stairs, killing one and two.
He wanted to make amends and atone for his sins, but he found in despair that the wife he had hurt so deeply looked at him with the same hatred from hell as he did.
She ran away, he chased her, but she couldn't fly.
But when she finally showed her trump card that could ruin his reputation, he smiled and held her hand holding the knife, stabbing himself in the heart:
"Wanwan, either use it to kill me and be completely free."
"Either... Forgive me."
